Both the EdgeWater 205CX 2011 and the EdgeWater 388CC 2012 are deep-V designs, both built in composite, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The EdgeWater 388CC 2012 measures 37,8 feet overall (2012), giving it roughly 17,3 additional feet of deck space compared to the EdgeWater 205CX 2011 at 20,5 feet (2011). Weight tells a clearer story for trailering families: the EdgeWater 388CC 2012 tips the scales at 9 600 lbs - 6 800 lbs less than the EdgeWater 205CX 2011 at 2 800 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 1 050 hp, the EdgeWater 388CC 2012 has a 825-hp advantage over the EdgeWater 205CX 2011's 225-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the EdgeWater 388CC 2012 carries 340 gallons versus 75 gallons in the EdgeWater 205CX 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The EdgeWater 388CC 2012 is rated for 11 passengers, while the EdgeWater 205CX 2011 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the EdgeWater 388CC 2012 could be the deciding factor.
